My invention relates-toa. railway track liner.

An important object or" the invention is to provide a track liner whichwill haveY a maximum holding action with the ballast,.to preventslippage of the liner during the operation.

A further object of the invention is to provide a tract: liner having amovableanchoring element or blade carried by the.v rail shifting bar orlever, which blade Will properly coact with the ballast withoutpreviously forming a" recess in the ballast to receive the blade.

A further object of the invention is to provide a trackA liner of theabove mentioned character having a base of relatively. large area whichcomer -ses the ballast beneath the base, due to the Weight of the tract;carredby the. base, and.. a ballast engaging anchoring element or; bladewhich is movable into; the, ballast andcompresses or crowds the ballasthorizontally toward the compressed portion of the ballast beneath thebase, thus effectively holding the liner against creeping in a directionopposite tothatin which tract; is to be shifted.

A further object of the invention is toprovide liner oi the abovementioned character which.

is a sell contained unit and .is adapted for use with various types otjacks.

Other objects and advantagesof ythe.invention will be apparentduring-the. course of the following description.

in the drawingsv wherein for the purpose of il lustration is v:shown apreferred embcdimentV of my invention a track `liner is shown comprisinga relatively large flatvbase lll'. This base may be about eight incheswide and thirteen inches long, although these dimensions may be varied,as found advantageous. The base. is continuous or imperforate to providethe maximum engagement with thev ballast whereby the .base will compress"the layer of vbellnet*beneath.' itl bsrvirtue oiathe y2 fact` that.thebase carriesfgthef, load of the track, whichis veryheavy. At itsvouter endy this base. lll carries. an upwardly; projecting flange orstop l l Near its inner end: the base vlill-'.has; apairol'verticalrapertured' knuckles. t2, formed integral therewith.

Arranged `above the4 base IB.; Ais a vertically swinging lever or bar'v|131, nrfnzided between its endand nearits longitudinal center with apending apertured knuckle. 141,; integral therewith, and pivotallyconnectedwitlr the knuckles l2 a pin l5. Formed' integralfwith the leveror bar i3 and' arranged above. itis. a Web lprojecting laterally beyondthelever I3, to, engage. with the 'base of. the rail, iorpforming acontact having a suitablearca..

Arranged atthe .innerend or4 the lever or bar it is a, ballast.engaging: anchoring elementvor blade ll, having-alarga. area. This blademay be eight inches-long and six..incheswide, although these dimensionsmay vary. Thisblade is, preferably imperforate so that. its relatively'large.` surface is continuous. The blade has. alower sharp beveled edgeI8; with its lower point'disposed outwardly with respect to the track ornext to the inner end of the base ld. The blade4v |11 is preferablyformed integral with the levery or-bar i3v which is positioned at theYlongitudinal-center of the blade El and near its-upperend. The blade-`-Il is arranged at an inclined anglewith respect to the lever-or bar I3,such as an agle-oi`25 from the perpendicu lar with respect to.the-leverwg although this angle may be somewhat varied, The blade Il iSvertically' inclined whenrthe lever I3 is in the horizontal rmsitionyand-this bladev extends from the base lil toward the loweredgev or theblade ll. The. lever orbar 13.115 provided. at. its outer end with. alack. engaging. yokeor. socket i9.. arranged beneath it., andprefrablyformedintesral there.- Wi h.

The liner is adapted ior use in connection with a lifting jack 20. otany Wellimown or preferred type. This lifting jack may heofthe ordinarytrack type, including a vertioaihousn's 2l vhaving a. base or foot,22.,whioh isplacednponthe base It and also. engagestheangeor stop il.'This jack includes. a vertically movable. toe- 23, which is raised andlowered bythe usual manually operated means. This toe engagesl withinthe yoke. I9', Y f

Theoperation of the liner is as.- follows:

When itis-desired to shifter line the track to the right, Fleizresz and3, the liner would be arranged beneathftheeleft grail; 'lt-fand between-a pair of cross-ties. It is usually necessary to remove some of theballast so that the implement may be inserted beneath the rail. Thelever or bar I3 is in the approximate horizontal position, when startingthe operation, and the anchoring blade ll is vertically inclined, andextends to the right toward its lower sharp edge I8 or from the basetil. The jack 20 is applied to the base IE and the toe 23 is moved intothe yoke or socket is. lThe liner is adjusted longitudinally so that theouter edge 124 of the rail base 25 is near the longitudinal center ofthe short arm of the lever, which short arm extends from the pivot l tothe yoke i9. When the jack is operated to raise the toe 23, the lever orbar I3 is swung vertically upon its pivot, the short arm of this leverrising and moving to the right, Figure 3. As the short arm rises, theweight of the track is transmitted to the base l0, which causes the baseto press down upon the ballast beneath it and form a iayer of highlycompressed ballast, the aggregates of which are not free to slip. Whilethis downward pressure of the base l 0 upon this ballast layer isoccurring, the anchoring blade l'l is swinging downwardly and alsomoving horizontally outwardly with respect to the track or toward thebase l 0. Since the lower edge of the blade il is sharp, it will readilydig into the ballast and will not overcome the downward pressure uponthe base I0, and will not materia-lly reduce the compression of theballast beneath this base IIJ. The blade Il' crowds or moves the ballastbetween it and the base IQ toward the base I and this ballast is pressedagainst the compressed layer ballast beneath the base lil. Hence theblade l1 acts against the ballast which it engages and since thisballast acts against the ballast compressed beneath the base il), theblade l1 eiectively holds the base E@ against creeping to the left, orin a direction from the track, which is a tendency caused by thepressure in that direction from the track. As the lever or bar I3 rises,the base 25 of the rail has its edge contacting with the web i6 at thepoint 2li, and the web does not slide down the inclined lever I3 as itmight be expected, but the base 25 and the entire adjacent section ofthe track is positively `shifted to the right a slight distance, to linethe track. The rail and crosstie are slightly lifted, but the lifting isincidental and is slight as it is not desired that the ballast shouldget beneath the cross-ties and disrupt the level surface of the track.Since the blade I1 is inclined, at the starting operation, itshorizontal moving or crowding of the ballast starts immedtravel by thetime the blade I'l is moved downf wardly to the vertical position orslightly past such vertical position. It is thus seen that when thelever i3 is inclined and is exerting the lateral pressure upon the base25 of the rail to shift the track laterally to theA right, the blade ll'will then be in the lowermost position and forced into the ballast, andpressing the ballast horizontally against the compressed ballast,beneath the base lli, whereby the base It cannot creep to the left.

lt is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatvarious changes in the shape, size, and arrangement of parts may bereferred to Without 4 departing from the spirit of my invention or thescope of the subjoined claims.
